Hyperbranched polymers with step-growth chemistries from transfer-dominated branching radical telomerisation (TBRT) of divinyl monomers

open access: hybridPolymer Chemistry, 2020
The commercially relevant synthesis of novel materials with step-growth backbones has been achieved by applying conventional chemistries to the radical telomerisation of divinyl monomers leading to high molecular weight branched polymers.

Controlling the pH-response of branched copolymer nanoprecipitates synthesised by transfer-dominated branching radical telomerisation (TBRT) through telogen chemistry and spatial distribution of tertiary amine functionality

open access: yesNanoscale Advances, 2022
Amine functionality offers the modification of polymer properties to enable stimuli-responsive behaviour, and this feature has been utilised in numerous studies of self-assembly and disassembly.

Structure-functional activity relationship of β-glucans from the perspective of immunomodulation : a mini-review [PDF]

open access: yes, 2020
β-Glucans are a heterogeneous group of glucose polymers with a common structure comprising a main chain of β-(1,3) and/or β-(1,4)-glucopyranosyl units, along with side chains with various branches and lengths.

The Thermal degradation of Bisphenol A Polycarbonate in Air [PDF]

open access: yes, 2005
The thermal degradation of polycarbonate in air was studied as a function of mass loss using TGA/FTIR, GC/MS and LC/MS. In the main degradation region, 480–560 °C, the assigned structures of smaller molecules and linear molecules that evolved in air were

Star polymers rupture induced by constant forces [PDF]

open access: yes, 2014
In this work, we study the breakage process of an unknotted three-arm star-shaped polymer when it is pulled from its free ends by a constant force. The star polymer configuration is described through an array of monomers coupled by anharmonic bonds ...
